When Did the Computer Era in Chess Start?

When did top pros start heavily integrating computer analysis with their own intuition and thinking in shaping their style of play and abilities?  

For example, was it post-Kramnik or pre-Kramnik?  

Also, do you think that those in the computer era have lost any skills or improved in any vs. those in the pre-computer era? 

Home / accessible chess programs that could beat a master were late 80s early 90s.   The mid 80s stuff just didnt have the processing power and memory and algorithms to do it .. The first one I saw was on an apple IIE and the program was on a cassette tape, and it took 20 min to move or more and was beatable by an unskilled kid (I was maybe 10 or 12 and had only just started at chess, '82 or so?).   Time I was in highschool I could analyze my games on a 386 with chessmaster 15 or so moves deep and I would think pro players had better machines and tools, that would have '90 - 91 ish. 

Time I was out of college fritz was a thing and everyone was all about the analysis.

Given that the ratings of the highest level players have never been as high as they are right now, I'd say it appears that computer analysis has helped human players quite a bit. Just the ability to search thousands of opening variations in seconds has to have had a tremendous benefit.

I thought it started in the 1960's, with Botvinnik.  He was an engineer by trade, and apparently one of his side projects was using the primitive computers of the time to analyze chess problems
